When would one use each of these words?
I know perdón is used to get someone's attention, and sometimes for "sorry".
I was taught to use "discúlpeme", for example, if accidentally bumping into someone.
However, the general distinction between these words seems a little confusing.
Ane while we're at it . . . what is the polite thing to say (anything') if someone sneezes? Of course, in English, it is the superstitiously-derived "Bless you".
